According to Swiss Meteo, north of the Alps, March 2018 was around one degree colder than average monthly temperatures between 1981 and 2010. South of the Alps it was one of the coldest in 30 years.
March 2017 was Switzerland’s hottest March since 1864, registering an average temperature 3 degrees above the norm, an average year-on-year monthly temperature difference of 4 degrees compared to March 2018. March 2017 was one of the two hottest since 1864.
The March cold snap does not mean climate change has changed course.
A temperature times series shows a trend line since 1981 that is more than 1 degree higher than the average for the period between 1864 and 1981.

One reason March was unusually cold this year was the greater cloud cover that came with a series of low pressure systems. One driver of this was an exceptional high pressure system over the arctic, which pushed cold weather further south than normal.
